Abstract: A two color printing ribbon mechanism for adding, calculating or the like machines in which the ribbon has two differently colored sections arranged end-to-end. Normally, a first and most frequently used ribbon section is held in contact with an inking device and the second less frequently used ribbon section is located at the printing line. During a cycle of the machine in which the first section is to be used for imprinting, and prior to the printing operation, the ribbon is moved endwise to locate the first section at the printing line and to move the second section into contact with a second and appropriately colored inking device. During a cycle in which the second section is to be used for imprinting, the ribbon moving mechanism is merely disabled, leaving the second ribbon section at the printing line during the printing operation.

Abstract: A keyboard switch device comprising rows and columns of intersecting wires conductors held taut and normally spaced slightly from each other by a separator sheet of non-conducting material having openings therein aligned with the intersections of at least certain of the conductors. The conductors are engaged by depressing different keys aligned with the conductor intersections and a relatively thick layer of soft elastomeric materialis interposed between the keys and conductors to normally hold the keys in raised position and to transmit pressure from the keys to engage the conductors. By merely changing the sizes, shapes and positions of the openings, the switching device can be made to produce different output coded signals. Also, by changing the configuration of the various rows and columns of conductors different switch matrix patterns can be produced.

Abstract: SIGNALS, A COUNTING DEVICE FOR APPLYING DRUM POSITION INDICATING SIGNALS TO EACH OF SAID COMPARING DEVICES, MEANS FOR APPLYING DATA SIGNALS TO EACH OF SAID COMPARING DEVICES, PULSING MEANS FOR CONCURRENTLY CAUSING STEPPING OF SAID COUNTING DEVICE AND SAID COUNTER, MEANS OPERABLE BY SAID STEPPER MOTOR DURING MOVEMENT OF A SECOND PART OF SAID PERIPHERY OF SAID DRUM PAST SAID PRINTING DEVICES FOR ADVANCING SAID RECORD MEDIUM FROM ONE LINE PRINTING POSITION TO A NEXT, MEANS CONTROLLED BY SAID DRUM AFTER SAID ADVANCEMENT OF SAID RECORD MEDIUM FOR PROVIDING AN INDEX SIGNAL, AND MEANS RESPONSIVE TO SAID INDEX SIGNAL FOR RENDERING SAID PULSING MEANS INEFFECTIVE.

1. A DATA PRINTER COMPRISING A ROTATABLE TYPE DRUM HAVING A PLURALITY OF COLUMNS OF TYPE CHARACTERS THEREON, SAID TYPE CHARACTERS EXTENDING ABOUT A FIRST PART ONLY OF THE PERIPHERY OF SAID DRUM, PRINTING DEVICE ASSOCIATED WITH RESPECTIVE ONES OF SAID COLUMNS FOR TRANSFERRING AN IMPRINT OF ANY OF SAID TYPE CHARACTERS IN RESPECTIVE ONES OF SAID ROWS ONTO A RECORD MEDIUM, A STEPPER MOTOR FOR INCREMENTALLY ROTATING SAID TYPE DRUM TO SUCCESSIVELY POSITION DIFFERENT ONES OF SAID TYPE CHARACTERS IN PRINTING RELATION TO SAID PRINTING DEVICES. COMPARING DEVICES FOR COMPARING DRUM POSITION INDICATING SIGNALS AND DATA SIGNALS AND FOR CAUSING OPERATION OF RESPECTIVE ONES OF SAID PRINTING DEVICES WHEN SAID DRUM POSITION INDICATING SIGNALS CORRESPOND TO SAID DATA
